This command creates drillholes from existing drillholes and surface entities or from a predefined Geologic Model file. You supply the x,y coordinate for the new drillhole and the routine will calculate the surface elevation and the strata elevations and attribute values based on the other drillholes and surface entities or the grids in the Geologic Model. This feature is useful for providing drillers with an estimate of the geologic column drilling exploration holes.
